ANTISLIPPING HORSESHOE ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed March 31, 1913. Serial No. 758,031.

To all whom it may concern: Be it known that 1, JAMES A. DAVIS, citizen of the United States, residing at WVaslr ington, District of Columbia, have invented. certain new and useful Improvements in Antislipping Horseshoe Attachments, of which the following is a specification.

This invention relates to devices adapted to be attached to horse shoes for the purpose of providing means for preventing slipping of the shoe upon snow, ice and wet concrete.

The primary object of my invention is the provision of a very simple and effective attachment of the character stated which mav be easily applied to or removed from a horse shoe and wherein the ealks may be readily applied to or removed from the attachment.

A further object of the invention is to provide means whereby the attachment may be firmly supported by a toe clamp and heel clamps, and whereby the heel clamps may be laterally adjusted so as to conform to the eculiarities of any individual hoof.

A still further object is to so construct the attachment that the distance between the toe calks and heel calks or between the toe clamp and the heel clamps may be adjustably varied to suit the shoe to different sizes of hoofs.

Another object of the invention is to so construct the attachment that it may adapt itself to hoofs lacking in bilateral symmetry.

A further object is to provide calks having a plurality of cutting edges and so mounted that each calk may be rotated to bring any one of the cutting edges into active position, and whereby the faces of the call: will be firmly supported to hold the calk against accidental rotary movement.

A still further object is to provide heel clamping members adjustable with relation to the body of the attachment.

Other objects will appear in the course of the following description.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawmgs, 111 which Figure l is an under side plan view of a horse shoe attachment constructed in accordance with my invention; Fig. 2 is a side elevation of the attachment applied to a hoof; Fig. 3 is a perspective view of the toe clamp of the attachment shown in Fig. 1; Fig. 1 is an under side plan View of a modified form of the attachment; Fig. 5 is a perspective view of a modified form of heel clamp with the attachment as shown in Fig. 4; Fig. 6 is a transverse section on the line G6 of Fig. 7; Fig. 7 is a transverse section on the line 7-7 of Fig. 6. Fig. 8 is a detail view of the tension bar shown in Fig. 4:.

Uorresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.-

The form of attachment illustrated in Figs. 1, 2 and 3 includes a front cross bar or plate designated 2. This plate at its ends is bent upward as at 3 over the edge of the shoe, and then is connected to an arcuate band 4 which fits over the toe of a hoof and forms a toe clamp whereby the forward end of the attachment is connected rigidly to the shoe. The plate 2 at its opposite end is formed with downwardly extending studs, as illustrated in Figs. 6 and 7, the studs being screw-threaded and designated 5, and being for the attachment of the front calks 7. These front calks 7 are triangular in form so as to provide a plurality of flat sides 8 and cutting edges 9. Any one of the fiat sides 8 is adapted to lie against and bear upon the plate 2 so that any one of the points may be extended downward. WVhen the calk is supported against the front plate 2, it will be support ed across its lower face so as to secure a thorough firm bearing.

Each face of the calk is formed with an aperture 10, these apertures or passages meeting centrally in the calk, as illustrated in Fig. 7. Passing through the stud 5 is a pin 11, this pin being preferably tapered, a laterally extending opening for the passage of this pin being made through the calk. Nhen the pin is forced through the calk and through the opening in the stud 5, the pin will act to clamp the calk rigidly to the stud by a wedging action. The end of the pin is intended to be bent over as at 12, but when it is desired to readjust the calk, it is only necessary to bend up the end 12, remove the pin, and readjust the call: so as to bring another aperture 10 in co-incidence with the stud 5.

Attached to the plate 2 at its middle and extending rearward therefrom is a rod 13 which is screw-threaded. Extending transversely across the rear portion of the shoe is a bar 14 formed with an elongated middle opening or passage 15. Extending through this passage is a rod 16 which is screw-threaded and which is in alinement with the rod 13. Connecting the rods 13 and 16, and engaging the screw-threaded portions thereof, is a nut or turn buckle 17. It will be evident that the rods 13 and 16 must be screw-threaded in reverse directions, so that when the turn -nut or buckle 17 is rotated in one direction, the rods 16 and 13 will be drawn together, and when rotated in the other direction, they will be forced apart. A set-nut 18 is also disposed upon the rod 13 and with the turn buckle 17 to prevent any accidental rotation of the latter.

The rod 16 is formed at its ends with a transverse tubular bore 19 interiorly screwthreaded at its ends for engagement with the screw-threaded shanks 20 of the heel engaging members 21. These members are preferably formed integral with the shanks 22. Each member extends downward behind the heel of the horse shoe A and then forward so as to hook over the heel, as illustrated in F ig. 2. Each of these heel engage ing members 21 is also formed with the forwardly projecting lug 23 which engages on the inside face of the heel as illustrated in Fig. 1. It will be noted that these members 21 may be adjusted independently of each other and relative to the axial line of the attachment, and that they may be rotated so that the lugs 23 of the, members may" have different angles with relation to the rod 16. Thus these heel engaging members may be accurately adjusted to fit any peculiar form of shoe or to fit any peculiarities in the horses hoof. It will further be observed that the members cannot move laterally by reason of the lugs 23, and that they will lock behind the heels of the shoe A, and when locked they will be clamped rigidly in position.

The cross bar 14, as before stated, is provided with an elongated opening 15 in its middle for the passage of the rod 16. Formed integral with the relatively large portions of this bar 14 are the laterally extending screw-threaded portions 2 1, these screw-threaded slight angle to the middle portion of the bar 1 1. Screwed upon the ends of these screwthreaded portions 2st are the calks 25. These calks are triangular in form, as previously stated, so as to provide three bearing faces and three cutting edges, the bearing faces being adapted to rest flat against the under face of the shoe immediately in front of the heel of the shoe. These calks have intee riorly screwrthreaded apertures for the reception of the screw threaded portions 24 .andthey are held in adjusted position by adapted to engage portions 24 extending at a,

means of set-nuts 26. It will be seen that not only may the calks be laterally adjusted independently of each other and with relation to the-axial line of the hoof or shoe, but

that the bar 14: may be shifted laterally with relation to the rod 16 so that the rod shall not pass through the middle of the bar 14, but to one side of the middle. This permits the shoe to fit hoofs in which there is no bilateral symmetry, and this is a very important feature inasmuch aswithout this means of adjustment, an attachment which will fit the hoof of one horse will not fit the hoof of another. It will further be noted thatthe heel engaging members 21 may be adjusted in correspondence with the adj ustment of the calks 25'. It will further be noted that after the calks 25 have been put in place and thetoe and heel clamps tightened' up, the rear portion. of the attachment may be drawn toward the forward portion of the attachment to tightly clamp the attachment upon a shoe by means of the turn buckle 17, and that this drawing together of the rods 13 and 16 does not affect the bar 14. This bar is held in adjusted position relative to the rod 16 by means of the setnut 27 which engages the screw-threads of the rod 16 and which bears against the inner face of the bar 1 1.

The calks illustrated are adapted to be rotated so as to present fresh sharp edges to the pavement, and thus the same calks may be used for a considerable length of time without grinding. It may be particularly noted that the calks have a large flat bearing area of a size equal to the base of the triangle forming the oalk, and that thus the calks are rigidly supported beneath the whole areaand cannot get out of position. The calks will not bend, they will not break, and when they become dull it is only necessary to readjust the calks to secure a new cutting edge until, all three of the cutting edges have been worn outv to an extent re.- quiring a new calk entirely. This new calk, of course, may be readily attached at any time.

In Figs. fl: and 5, I have shown another form of my. construction, similar in its broad features to the construction shown in Figs. 1 and 2. In this construction, however, the position of. therear calks may be adjusted relatively to the heel of the shoe and inde pendently of the tension rod which is not possible in the construction illustrated in Figs. 1 and 2. This adjustment is secured by the provision of links connecting with and engaging over the heels of the shoe. In Fig. 4, B designates the horse shoe and 26 designates a relatively small plate folded upon itself as indicated in Fig. 8. Pivoted to this plate by means of bolts 27, and extending radially outward from these bolts, are the shanks28 of hooks 29 which engage over the toe of the shoe and form toe clamps. These hooks 29 are reduced each at its middle portion, as at 30, and rotatably mounted upon the reduced portions of the hooks or toe clamps are the triangular calks 31 constructed in the same manner as the calks 25 previously described. The bases of these calks rest solidly against the under side of the shoe, and the calks are held from any lateral movement by the fact that they are disposed upon the reduced portion of the shank 28. In the construction of this hook, the portion which forms the hook proper is reduced and inserted in an opening in the extremity of the portion 28, this inner reduced end being pinned to the portion 28. By driving out the pin, the outer section of the shank may be removed from the inner section, and thus the calk removed and replaced. The plate 26 is extended rearward in the form of a rod 32, the rear end of which is screw-threaded as at 33 and provided with a set-nut 34. The transverse bar 35 is constructed in the same manner as the bar 14, and is formed with the laterally extending angular shanks 36. Threaded on these shanks are the calks 37 which are constructed in the same manner as the calks 35.. Disposed between the calks 37 and setnuts 38 mounted on the shanks 36 are the rearwardly extending heel clamping links 39, one of which is shown in Fig. 5. These links comprise essentially a loop portion 40, preferably divided by transverse bars 41 to .provide a plurality of openings 42, the rear of the loop being extended rearward, then laterally turned, as at 43, and then upwardly bent and forwardly curved as at 44. The loop portion of the link extends along the inside edge of the shoe, while the hook por tion extends over the heel and clamps over the same. The shanks 36 of the bar 35 extend through any one of the openings 42 of the loop 40, and thus the rear calks 37 may be adjusted to any one of three separate positions, either immediately against the heel, near the middle of the shoe, as illustrated in Fig. 4, or at an intermediate point, and, at the same time, the heel clamping hooks 39 may be drawn tightly into locking engagement with the heel of the shoe by turning up on the nut 34. The portion 35 is transversely slotted, as previously described for the bar 14, so as to permit the heel clamps and heel calks to be adjusted on shoes where the cusps of the shoe are at varying distances from the axial center of the shoe. This form of shoe is used in the same manner as the shoe previously described. It may be readily adjusted, removed or replaced. It has this advantage over the shoe first described, that the pivoted links or shanks 28 permit the toe clamping members to be adjusted near to or farther from each other to fit any particular form of hoof. It is further to be noted with regard to both of these shoes that the attachment never acts to spread the heel of the shoe, nor draw the cusps of the shoe together, but when once adjusted it holds the shoe from lateral displacement and reinforces the hoof against shock.

In order to prevent snow or mud from balling up within the hoof, I preferably use in connection with the horseshoe attachment a shield designated 45 and illustrated in Figs. 1 and 2. This shield may be made of thin sheet metal or any suitable material of like character and is provided upon its upper face with inwardly projecting lugs 46 through which the rods 13 and 16 extend, or if the shield is used with the construction shown in Fig. 4 through which the rod 32 extends. A shield of this character is particularly necessary inasmuch as the mechanism of the attachment is liable to collect snow and mud. This shield is further of value in that it protects the tender portion of the horses hoof, and also permits the hoof to be packed with cotton waste or like material whereby medicaments may be ap plied directly to the hoof as is often necessary.

Having thus described the invention what is claimed as new is l. A horseshoe attachment of the character described, including a toe clamp, oppositely disposed heel clamps, means for drawing the heel clamps toward the toe clamp, and means for laterally adjusting the heel clamps with relation to the means for draw ing the heel clamps toward the toe clamp.

A horseshoe attachment of the character described, including toe calks, heel clamps, a transverse member to which the heel calks are ope "atively connected, a tightening member engaging the transverse member to draw the heel calks toward the toe clamps, said transverse member being longitudinally adjustable upon the tightening member and laterally adjustable independently of and with relation thereto, and said.

heel clamps being provided with forwardly extending lugs engaging the inside faces of the shoe heels and operatively connected to the tightening member.

7. A horseshoe attachment of the character described, including toe clamps, heel clamps, a tightening member connecting the toe and heel clamps, a heel calk carrymg member, heel calks carried thereby, and

clamps, a tightening member, a transverselyextending member through which the tight ening member passes, said member having screw threaded laterally extending shanks,
